Learning to walk again: Thusha, pictured before she was shot, left, and while undergoing physio during her recovery

Unconscious
for a week, the schoolgirl was kept alive on a life support machine and
her parents were warned she had only a 50-50 chance of survival.

Once her life was out of danger,
Thusha was transferred to Stoke Mandeville Hospital in Buckinghamshire
and began intensive physiotherapy for the damage to her spinal cord from
the bullet.

Now she can
stand with the help of her walking frame and physiotherapists help her
to walk in a harness which carries her weight, to teach her body ‘muscle
memory’ and help her spinal cord to make new nerve connections.

Every
step takes concentration and massive effort, but for her family it is
like watching ‘a miracle’, her father told the Sunday Mirror.

Her mother Sharmila Kamaleswaran, 36, told the newspaper: ‘Last month we came home one day to find a letter from the hospital about Thusha’s treatment.

‘It came as a total shock, but it said that because of her amazing progress they’d changed their minds and she would definitely walk again. We were so happy.'
